' In Germany August 9, 1938 Claims. (01. 216-54) 'The subject of the present invention is apparatus for applying revenue duty labels or like strips to the narrow sides of packages by means of adhesive. I

5 Most of the known apparatus of this kind operate in such manner that the revenue duty label, to which adhesive has previously been applied, is brought by means of grippers or the like into. the delivery track of the packages. so that it is caused to bear against the package atthe ends, whereupon, in the further course of the delivery movement of the package, the revenue duty strip is applied to its longitudinal sides, and, if desired, is also pressed on to the rear side. Various devices have been proposed for obtaining a uniform, ilrm pressing of the part of the revenue duty 'strip which is applied to the end-sides oi the package. for example automatically controlled rams or flexible counter surlaw. In other cases, by means of special devices the revenue duty label is relatively strongly stretched between tongs, so that to a'certain extent it is itself a temporary abutment. 3

All these devices complicate and increase the cost of the construction of the machine, and moreover they reduce the working speed of the machine. The ilexiblyreceding supporting surfaces generally require a lateral turning of the movement of delivery, while, on the other hand,

diiilculty isexperienced in obtaining the correcttension of the strip between the tongs, a a duly great tension can lead to tearing, while if the adjustment is too loose, creases may form when the strip is attached.

Now, in order to avoid the aforesaid disad-mvantages, according to this invention the pro-- cedure is such that, in a continuous guide track the foremost package is brought into and kept temporarily in such a position that it serves as a supporting surface for the strip to be secured to the end 0! the following package, and which on the further advance movement is pressed in known manner on the longitudinal sides and; if desired, also on the rear side 0! the package. Thus it becomes possible to complete the application of revenue duty labels on the packages in question in a single rectilinear path, while at the same time it is possible to dispense with special pressing devices of the type specified above and also to simplify the type .01 construction.

Devices of widely varying type can be used. A typical example of such an apparatus for applying revenue duty labels is illustrated in the It annexed drawings, inwhich:

in the container.

Fig. 1 is a side view of an apparatus for applying a revenue duty label.

Fig. 2 is a plan of the machine.

Fig. 3 is a plan of an additional device on a machine for applying a revenue duty strip, for 5 applying the ends of the said strip to the rear narrow sides of the package.

In the machine shown, the revenue duty strips are accommodated in a swinging container a, below which is located a revolving segmental 10 roller 2) provided with a bar or segment 0. At the side of the roller b there is fitted a glue container d and a gluing roller which, when the roller b revolves, comes into contact with the projecting segment 0 and applies glue thereto. 15 On the further rotation of the roller 1) the segment 0 engages the swinging container at and makes rubbing contact with the lowermost strip Thus the bottom revenue duty strip is removed from the container :2 and ad- 2 heres to the bar c:

Spaced apart at one side of the roller b there are provided gripper jaws e which swing up and down, and which are controlled in such manner that in their raised position they seize the ends of the revenue duty strip which project laterally from the segment c, and move downwards on to a delivery table I in the path of the packages a to which the revenue duty strip is to be applied.

At the end of this downward movement, the 30 revenue duty strips arrive on bearing surfaces h which are fitted at the side or the delivery track of the package g and are placed endwise on the revenue duty strip. The surfaces of application are arranged adjustably so that the revenue duty 35 strips can be secured somewhat higher or lower on the edge of the box. To the bearing surface h for the revenue duty strip there is connected a guide track It provided with brushes and effectin: for the lateral brushing 'of the ends of the strips. v

For advancing the packages a there is provided .a conveyer device in the form of an endless conveyer chain m on which abutments n are pivotally fixed. These abutments n are guided in a recess in the table t which extends to the immediate vicinity of the entrance oi the guide 1 channel It and there is interrupted by a trans-' versely disposed recess 0. As soon as the sbut- 50 i ments arrive at this recess the constraint ceases. and on the further movement of the conveyer chain 111. the abutments can swing freely downwards, leaving the package 9 in the advanced position in each particular case, in 85 The mode of operation of the apparatus is as follows: The'revenue duty strip removed from the segmental roller. 2), by means of the gripping edgewise on the bearing surtongs e, is placed face h, and kept there until the advanced package strikes against the revenue duty strip.

Jaw of the gripper is controlled by a cam p in such manner that. in the lower position, the ,iavr is open, so that when the package strikes revenue duty strip. the ends of the latter can slide out of the Jaws until the box with the freshly coated revenue duty ship strikes directly against the previously treated box. Thus the end of the revenue duty strip is pressed quite smooth, while on the intermittent further movement'of the package 9' in the channel It the revenue duty stripis brushed firmly on sides. The box remains for the time being at a the entry oi the channel in the position shown in Fig. 1, until the operation has been repeated and a new box comes into position and thrusts the previously agglutinated box further forward.

Finally, at the end of the table the boxes fall on to aconveyer belt turther conveyance.

If it is necessary for the ends of the revenue dutystriptobesecuredalsototherearsideoi roller cooperating g the latter along said the box, there may knives 4 which are guided on both sides of the guide track It, and which are advanced laterally in succession by means of a cam device or they like; thereby the projecting ends of the strip are pressed against the rear side of the package, as shown in Fig. 3. Y i

The invention is not limited to theform of 00a, structions shown in the drawings, but other known devices may be used for feeding the revenue duty strip, for advancing the packages and also for pressing the strips against the sides and also against the rear wall; the main essential h thein arrangement and co-ordination with one another so that they bring the foremost package into and keep it temporarily in such a position that it can serve as a supporting surface for the strip to be secured to'the end-side of the following package.
